Second-generation descendants of the famous wandering wolf OR-7 were just discovered — and boy, are they cute.

OR-7, who left his Oregon pack in 2011, was spotted travelling through Butte County five years ago. In 2015, a wolf he had fathered was spotted in Lassen County travelling with another wolf.

That son has now fathered at least three pups, captured on camera by U.S. Forest Service Cameras on Friday. This means California, which had no recorded wolves in the state for about 90 years before OR-7, now has two established wolf packs – the Shasta Pack and recently formed Lassen Pack. Gray wolves are currently both state and federally listed as endangered.

The Shasta Pack produced five pups in Siskiyou County in 2015. The whereabouts of those pups are unknown, aside from one that was detected in northwestern Nevada last fall.

Early this May, biologists from the U.S. Forest Service had sniffed out the presence of the wolves in Lassen National Forest. On Friday, after 12 days of trapping attempts, California Department of Fish and Wildlife biologists captured a 75-pound adult female gray wolf, according to a press release. After a thorough exam — including collection of genetic and other biological samples — she was collared and released.

“The anesthesia and collaring process went smoothly and the wolf was in excellent condition,” said Fish and Wildlife Senior Wildlife Veterinarian Dr. Deana Clifford in a press release. “Furthermore, our physical examination indicated that she had given birth to pups this spring.”

The paternity of OR-7’s son, her mate, was verified from genetics detected in scat samples — he originated from Oregon’s Rogue Pack, of which OR-7 is the breeding male.

On Saturday, Fish and Wildlife biologists returned to the field for a follow-up check on the female, encountering the tracks of what appeared to be wolf pups. That’s when the (adorable) trail camera footage was found of the young wolves playing.

The tracking collar on the Lassen Pack female will collect data related to her activity, survival, reproduction and prey preferences, according to Fish and Wildlife.

The Lassen Pack regularly crosses both public and private lands, including industrial timberlands. According to Fish and Wildlife, the collar may help minimize wolf and livestock conflicts, as it provides information about the pack’s location relative to livestock and ranch lands.

Though most of the pack’s known activity has been in western Lassen County, some tracks have also been found in Plumas County.
